Summary: Non-pharmaceutical interventions (NPIs) and COVID-19 vaccination have been implemented concurrently, making their relative effects difficult to measure. Here, the authors show that effects of NPIs reduced as vaccine coverage increased, but that NPIs could still be important in the context of more transmissible variants.

Summary: This retrospective cohort study in Israel found that receiving at least one dose of the BNT162b2 vaccine was associated with a significantly lower risk of recurrent infection among patients who had recovered from Covid-19. Vaccine effectiveness was similar for one dose and two doses.

Summary: There are gaps in COVID-19 vaccine coverage in the United States, with lower vaccination rates among individuals with previous COVID-19 diagnoses and higher vaccine hesitancy among them. It is important to focus on adults who receive a COVID-19 diagnosis during clinic visits or at the time of discharge if hospitalized and educate the public about the value of being vaccinated regardless of previous infection.

Summary: This study conducted real-life research on healthcare workers in Mumbai, India, and found that full vaccination significantly reduced the rate of infection, especially severe infections. Even among those who were infected, the hospitalization rate was very low and there were no deaths. The effectiveness of the vaccine was higher for those who had previous infection with COVID-19 and completed full vaccination.

Summary: Diagnostics play a crucial role in the response to the COVID-19 pandemic. Molecular tests like PCR are recommended for confirming diagnosis in symptomatic individuals, while antigen rapid detection tests have the advantage of being easier to perform with faster results and lower cost. Antibody tests can inform public policy but should not be used as proof of immunity. All three types of tests continue to be important in transitioning from pandemic response to control.

Summary: The study confirms the effectiveness of COVID-19 vaccines in preventing infection and severe symptoms among healthcare workers in Mumbai, India. Complete vaccination reduces the infection rate, especially during the severe delta wave. Prior infection with COVID-19 and complete vaccination significantly increase the effectiveness of infection prevention.

Summary: The reinfection rate of SARS-CoV-2 is low, and the severity of the first and second episodes of infection is similar. The severity of the second episode of COVID-19 is not higher than that of the first infection, even for patients with antibodies.

Summary: COVID-19 infection can lead to a range of symptoms, from asymptomatic cases to severe inflammation with multiorgan damage. The severity of the disease is determined by the patient's immune response and excessive release of inflammatory mediators can result in a cytokine storm. Asthma patients show variable outcomes due to the different immune responses, with Th2 response playing a role in preventing cytokine storms in COVID-19.

Summary: The ratio of COVID-19-attributable deaths versus true COVID-19 deaths depends on various factors and is currently leading to under-counting in some countries while possibly over-counting in others. Caution is needed in attributing deaths in syndemics like COVID-19.

Summary: The COVID-19 pandemic continues to pose a devastating threat to social life and economics, with the rise in active cases attributed to the emergence of new SARS-CoV-2 variants. While reinfection cases worldwide have been limited, most reinfected patients were asymptomatic, and the reasons for reinfection included immunological factors. Vaccines have shown effectiveness in preventing severe illness from different variants.

Summary: This study investigated the duration and effectiveness of immunity among healthcare workers in the United Kingdom. It found that two doses of the BNT162b2 vaccine provided high short-term protection against SARS-CoV-2 infection, but this protection significantly decreased after six months. However, infection-acquired immunity boosted by vaccination remained high, even more than one year after infection.

Summary: Studies in Czech Republic show that the effectiveness of COVID-19 vaccines declines after 7-8 months, with a decrease in protection against infection, hospitalization, and death. Boosters are found to restore the original vaccine effectiveness, and post-infection immunity also diminishes over time.
